如何在Angular中做单选按钮

Question

这是我的代码。当我提交 switchColors 时，服务器为其返回 undefined。这是怎么回事？

另外我应该如何在我的控制器中启动 $scope.swichColors？目前我有 $scope.switchColors = '';

<label class="radio-inline">
    <input type="radio" ng-model="$parent.switchColors" value = "yes" >Yes</input>
</label>

<label class="radio-inline">
    <input type= "radio" ng-model = "$parent.switchColors" value = "no" >No</input>
</label>

Answer 1

尝试使用 ng-value 代替 value

 <label class="radio-inline">
        <input type="radio" ng-model="$parent.switchColors" ng-value = "yes" >Yes</input>
    </label>

    <label class="radio-inline">
        <input type= "radio" ng-model = "$parent.switchColors" ng-value = "no" >No</input>
    </label>
